COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 715,574, dated December 9, 1902. Application filed January 8, 1902. Serial Nn. 88,823. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN E.IIAARMANN, a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented a new and Improved Cooling Apparatus, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for cooling fluids, particularly liquid or semiliquid substances. It is especially adapted for use in distilleries, starch and sugar factories,

I breweries, glucose-works, and other manufactories where material is cooked or boiled.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

' Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is an elevational view with parts in section on the line 1 1 of Fig. 2. Fig. 2 is a sectional View on the line 2 2 of Fig. 1, and Fig. 3 is a detail section on the line 3 3 of Fig. 1. 1

10 indicates a stand-pipe or hollow column, which may be of any length and form desired and which isopen at its lower end to lead "01f the material passing therethrough.

11 indicates a pipe passing from the cookers or apparatus in which the fluid is heated. This pipepasses down through a cap 12, fastened rigidly on the upper end of the pipe 10,

and the pipe 11 is provided with a funnelshaped or flared discharge end 14:, so as to cause the fluid as it passes from the pipe to be spread or sprayed out throughout the en tire area of the enlarged coolingpipe 10. The cap- 12 is provided with a number of orifices 15 therein, through which air is adapted to be drawn into the pipe 10', and also has an annular internal bead 12 near its bottom. Within the cap is arranged an annular regulating-rin g 16, which rests loosely on the bead and in which are formed openings 17, adapted to register with the-openings 15in the cap .12.

18 indicates a knob connected to this ring 16 and projecting through a slot 19in the cap 12. By means of this knob the ring 16 may ings in the cap 12 into the cooling-pipe 10 and.

to be drawn down through the same'into the liquid. Thusaste'adycurrent of air is drawn in with the liquid and the liquid is spread or divided, so that the air may exert its cooling influence upon all the particles of the liquid.

If desired, additional airinlet openings may be formed atvarious points along the length of the cooling-pipe, thus increasing the cooling effect. I have not illustrated this arrangement, since it will be obvious to skilled mechanics. Also the air-inlet may be omitted entirely and the cooling done by contact with the sides of the pipe.

Various changes in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to allforms of the invention as may lie within the intent of my claims.

.Having thus described my invention, I claim as new and desire to secure by Letters Patent-'- 1. An apparatus for cooling liquids, comprising an elongated body portion or coolingchamber open at each end, a cap fastened to the upper end of said body portion and having at its' lower .portion an annular interior bead, and having air-inlet openings in its vertical side, an orificed regulator-band located in the cap and bearing on the said head thereof and movable in the cap to regulate the admission of air, means extending to the outside of the cap to facilitate the operation of the regulator-band, and a liquid-supply pipe passing through the top of the cap into the same and discharging into the body portion longitudinally thereof.

2. Anapparatus for cooling liquids, comprising an elongated body portion or coolingchamber, a cap fastened to and communicating with the upper end of the same, said cap havingaclosed top and orifices inits vertical In testimony whereof I have signed iny sides, avertica11y-disposed orificed regulatorname to this specification in the presence of to band movably carried in the cap and lying two subscribing Witnesses.

against the orificed sides of the cap, for the 5 purpose specified, and a liquid-supply pipe JOHN HAARMANN' passing through the top of the cap and extend- Witnesses: ing downward into the upper end of the body HARRY G. JORDAN, portion or cooling-chamber. BYRON R. HASTINGS.
